They sent out a big batch in early Feb, and nothing since as far as I know, Geez, I interviewed on December 4th and I am still waiting to hear something! The interview invitation and acceptablility letter came so fast I really had my hopes up, pero ya no. 🙁
A more recent interviewee on this board says her acceptable letter stated people would hear in May or June, so don't get too antsy just yet.
Down with BU! (I'm really bitter today, huh! That's because the Kaplan people were visiting my school and made me realize the torture I may have to endure if I don't get in soon!)
